Definitions

  • the invention relates to a medical instrument for treatment of biological tissue by means of unfocused pressure waves.
  • Such instruments serve by means of pressure or shock waves the healing process of bone fractures and bone defects but also to accelerate in the periodontal disease or at all to get started first. Another application is the treatment pain in tendon attachments.
  • extracorporeal Pressure wave devices will be the focal point of an acoustic Reflectors, e.g. by means of a spark discharge, as in the German Offenlegungsschrift DE 23 51 247 A, a pulsed pressure or shock wave generated by the Reflector is focused on the object to be irradiated. It It is assumed that with the help of the pressure waves micro damages be generated in the biological tissue, which the body to regeneration measures cause.
  • Such known pressure wave devices have a closely localized Focus area in which alone has a therapeutic effect is observed. This is due to the fact that these pressure wave devices - so-called extracorporeal lithotriptors - for the Smash of body stones were developed. At this Applying all the energy in a small area, in In this case, on the body stone to be destroyed, bundled. For a satisfactory treatment result for bone fractures and In pain therapy, however, usually a larger area be evenly sonicated. This requires a complex Movement mechanism and is also by repeated visits the treatment position very time-consuming.
  • German patent application DE 197 25 477 A1 is a Device in which unfocused with a transmission element, mechanically generated pressure waves in biological tissue be coupled. The user must be blunt Direct the transfer element to the treatment site. This very much However, simply constructed instrument has the consequence that the Movement of the transmission element - even if they are only on a change in length limited by the influence of a pressure wave - is unavoidable. For applications where a such device is applied to the skin surface like the Load by the deflection of the transmission element, such as Redness and slight swelling, justifiable. In the treatment a periodontal disease, on the other hand, would require such an instrument be placed on the gum, which this burden not withstand.
  • Document WO-A-94/17771 discloses a medical instrument having a pressure wave generating means and a pressure chamber that transfers pressure waves and couples them into biological tissue, wherein the pressure chamber consists of an elongated, liquid-filled channel, and wherein a linearly reciprocable impact part couples pressure waves into the fluid of the pressure chamber.
